Description
Aquipond Blue Marine is a concentrated, 100% organic blue dye designed for ponds, lakes and large bodies of water. It tints the water a sky blue that filters sunlight: less light reaches the bottom, which limits the conditions that favour the growth of aquatic vegetation. Blue Marine is the same blue dye as Blue Lake, offered here in two pack sizes.
How the dye works
Aquatic plants and algae need light for photosynthesis. In clear, shallow water, sunlight reaches the bottom and encourages their growth. The dye filters part of this light, including UV rays, so submerged vegetation has less light energy available to grow.

It is used in bodies of water where submerged plants grow, such as water milfoil, Canadian waterweed, Brazilian waterweed (Egeria densa), spiny naiad (Najas major), stoneworts or hornwort, as well as filamentous or microscopic algae.
The benefits for your pond
- Less light at the bottom: conditions less favourable to submerged vegetation.
- Attractive sky-blue tint: a cleaner, brighter-looking body of water.
- Organic and biodegradable: non-toxic to fish and to people, including swimming and diving.
- Clean, quick use: the water-soluble sachet dissolves directly in the water.
How to use
Calculate the surface area of your pond, then place the required number of sachets directly in the water without opening them: the water-soluble film dissolves and releases the dye. Repeat every 4 to 6 weeks, i.e. about 6 applications per year.
What dose for my pond?
One 100 g sachet per application: 1 sachet per 1,000 m² where algae are present, 2 sachets per 1,000 m² where aquatic plants are present, every 4 to 6 weeks.
| Surface | Algae | Aquatic plants |
|---|---|---|
| 1,000 m² | 1 sachet | 2 sachets |
| 2,000 m² | 2 sachets | 4 sachets |
| 5,000 m² | 5 sachets | 10 sachets |
| 10,000 m² (1 ha) | 10 sachets | 20 sachets |
This pack: 1 kg variant = 10 × 100 g sachets (one application for 10,000 m² where algae are present or 5,000 m² of aquatic plants); 5 kg variant = 50 × 100 g sachets (one application for 50,000 m² or 25,000 m²).
Good to know
- Suitable for ponds, lakes, garden ponds and bodies of water.
- The dye works on light: it does not replace reducing nutrient input or maintaining the pond.
Tip: handle the sachets with dry hands and keep them dry until use: their film is water-soluble.
